Cadbury salmonella scare probed

An investigation is under way after Cadbury withdrew a million chocolate bars which may have been contaminated with a rare strain of salmonella.

The company says the recall - while the Food Standards Agency and the Health Protection Agency investigate - is precautionary and that the risk is low.

But a bacteriologist says there is no safe level for salmonella in chocolate.

The possible contamination has been traced to a leaking pipe at a Cadbury's plant in Herefordshire in January. Samples were sent to an independent laboratory after the leak was discovered at the Marlbrook plant, and the montevideo strain of salmonella was identified.
